This invention relates to improvements in building covering construction, and more particularly of the construction, assembling and application of slabs or bricks for mounting-preformal veneer panels to form the siding of a building.

Objects backing under pressure on one -sidej thereof; to provide for more adequate and waterproof, nailing of the slabs in place; to apply the assembled4 veneer panels to. thesides, next window openings, and corners of a building and anchor the same thereto; to provide a waterproof and heatproof construction; to secure simplicity of construction, operation and minimum cost to manufacture; and to obtain other advantages and results as; may be brought out in the following description.

Description In the specific embodiment of the invention illustrated in said drawing, and referring initially to the general run of slabs or bricks constituting the major portion of a building construction as to be enabled to mount slabs| or. bricksl to they shown in'Fgures 1` to 3 inclusive, the reference numeral Ill designates the siding or other portion of a building already constructed to which the veneer or covering of the present invention is to be applied. The veneer is preferably made up 5 of a multiple assembly or unit of stepped construction of which a multiple of slabs are held togetherand applied to the building at one time. Forthis purpose, a suitable backing lI is pro vided. It may also be referred to as 'a base or 10 foundation panel, and preferably formed of rigid insulating material of any well known commercial -type such as compressed iibrous or cellulose material. This base or panel is of a stepped y construction corresponding to the stepped ar- 15 rangement of the several slabs applied thereto. On the front face of this panel is applied suitable adhesive material or cement I2' to which the several. slabs used to form the unit are applied at the factory so as to be permanently held upon the panel. The reverse or back side of the panel is likewise coated with a layer I3 of cement or other adhesive which can be activated or otherwise caused to :adhere to the building or siding I0 during the construction operation. This adhesive layer-can be of any well known material, of which asphalt, latex, aluminum cement and the like are examples.

Each of the general run of slabs preferably have two edges thereon undercut and two opposite edges projecting beyond the face area of the slab. The face area M of the slab preferably has the usual size and shape of the face of a brick and is integral with the rears. I5 of the slab which has an area enough greater than the face area to make up the necessary spacing of the face areas to accommodate pointing cement between the face areas. It will be noted by reference to Figures 1, 2, and 3 that the specific showing provides an undercut I6 along the top edge of the slab so that the back area I5 provides an upper edge which is at a lower elevation than the upper edge of the front area. The back area I5 projects below the front area Ifl a greater distance preferably substantially twice as great than the undercut I6 of the next lower section, and thereby constituting a flange I'I and thus there is pointing space I8 between adjacent front areas, but the lower edge o-f the back area I5 rests upon the upper edge of the back area of the slab next below and thus a positive spacing of the front areas of successive slabs is obtained and the pointing space I8 is necessarily uniform throughout the entire structure. The relationship of undercut and projecting flange I'I above described 55 as regards upper and lower edges of the slabs is duplicated at ends of the slabs so that the projecting ange of each back area at the end of one brick will rest behind the undercut of the next adjacent slab and obtain perfect spacing of juxtaposed slabs. The fact that the back areas are directly in contact with each other and are overlapped with front areas I4, not only obtains the aforementioned even spacing, but obtains a very solid land waterproof construction of the entire back area. After the building is cornpleted, or at least after the number of units have been applied, the pointing space I8 may be filled With suitable pointing cement I9.

As a feature of the present invention, I pro- 'de in the projecting flange II nail holes 2|) for `eception of nails 2| driven into the building after the unit is put in place and caused to adere to the building. These nails 2| preferably t loosely Within the holes 20 and are furthermore not driven entirely home, as will be observed in Figs. 2 and 3. The adhesive layer I3 adequately holds the unit in place during the construction period and the pointing cement I9 is applied so as to iill up the holes Iaround the nails and over the heads thereof as clearly indicated in Figure 3. 'I'his construction will therefore enable the nails to be inserted without injury to the bricks and yet will obtain a permanent mounting of the slab by means of the nails and adequate waterproofing of the nail holes and joints by the pointing cement. 'I'he overlapping and underlapping of the several slabs, with the pointing cement obtains a very impervious and heat resisting veneer in itself, but these characteristics are greatly improved by the presence of the panel II and the waterproof and heat resisting veneer adhesive layers I2 and I3.

For special purposes, such as at the corners of buildings, I may provide individual corner pieces such as shown in Figures 4 and 5, which can be of appropriate variance in length to build up the corner with overlapping and interftting 45 relation to the bricks of the unit structure above .ldescribed The corner slabs of Figures 4 and 5 are similar to the slabs heretofore described, having front areas I4 and back areas I5 together with undercuts I6 and projecting flanges Il and nail holes 2-IJ all as above described. 'Ihe principal dierence is that these corner slabs also have portions I4' and I5' at one end thereof which project at right angles to the portions I4 and I5 already described.

Likewise, for special purposes, such as around Window openings and elsewhere, a modification of the angular formation of Figures 4 and 5 may be made to eliminate the projecting flange at one end of one of the angular portions. Such construction is shown in Figures 6 and 7 wherein portions I 4b and I5u represent the face and back portions respectively with the back portion I5b providing a depending flange I'Ib but with the end edge 22 of both portions juxtaposed or at a common plane. The angular portions I 4 and I 5c o-f this slab are here shown as having the end undercut for intertting with projecting flanges and other slabs.

I claim:

A slab of the character described for veneer purposes having an adhesive backing adapted to be attached to a wall of a building and comprising an integral face portion and back portion of brick, the face portion of said brick projecting at the top edge and one side edge beyond similar edges of the back portions, and the back portion projecting beyond the bottom edge and opposite side edge a distance substantially -twice as great as the aforementioned projections of the face portion at the said top and first said side edges of beyond the back portion, said larger projecting back portions having nail holes adjacent the bottom edge and one side edge of the face portion adapted to receive nails of a diameter smaller than said nail holes and driving the nails into the building Wall for rigidly securing said slab to Isaid building wall and the heads of said nails protruding slightly outward from the holes thereby allowing lling in the space surrounding said nails.
